Dear Randy,

       If you tell us what type of sensor you are using and something about 
your setup, where the sensor is, how long the cables are, the size of the 
power line towers, your observations of the effects, etc., we may be able to 
help. The short answer is that interference is possible. There are two 
types:- electrical / RF interference / switching transients and wind sway on 
the electricity pylons. However, you can also get wind generated effects on a 
house and from nearby trees. I put a wind speed sensor outside and was able 
to clearly identify wind effects on my very solidly built old house.      

       Regards,

       Chris Chapman

gh voltage power lines have an effect on how my sensor works?

The lines are about 250-300 feet away.
